To all whom t may concern:

Be it known that I, WILLIAM JOSEPH RIDER, av subject of the King of Great Britain and Ireland, residin at Gardenside, Oakwood Road, Horley, 1n the county of Sussex, England, have inventedv new and useful Improvements in Seats, of which the following is a specification.

The invention relates to seats, and consists of improvements which are particularly intended for use with the seats used in cinemas, theaters and the like, though they may be also applied to other seats and chairs.

The seats used in cinemas, theaters and the like are arrangedin rows, and the distance between each row is made as narrow as vpossible in order that the seating accommodation shall be as large as possible.

Owing to the narrow width of the space between successive rows of seats, when a person has topass to an unoccupied seat other than a seat at one of the ends of a row of seats it is necessary for one or more of the persons already seated to rise in order to allow the newcomer to reach his seat. The same holds good when a person, under the same circumstances, leaves hisl seat. The necessity of said person or persons having to rise, which is also necessary when tip-up seats are used, is a great inconvenience to the occupants of the seats in rear of the row in question, as their view of the screen, stage or platform is obstructed for some considerable time. i

With a view to obviating the above referred to inconvenience I devised a construction of seat which renders it unnecessary for the occupants of cinema and like seats to rise when persons'vvish to pass, as aforesaid, to unoccupied seats yor to leave their seats. With this construction of seat, see the s ecification of my ap lication for Letters atent of the United tates, Serial No. 410,184, dated September 14th, 1920, al1 that the occupant of'a seat has to do to allow a person to pass to an unoccupied seat or to leave his seat is to either swing his legs to vthe right or left or while the seat is in its normal position to merely moveit backward.

The present 1nvent1on cons1sts of an 1m- `proved construction of seat in which the mechanism employed is not only of simpler nature and cheaper to manufacture than the mechanism described in said specification but will also allow the seat to be moved 'I backward at any time.

The invention is illustrated by the accom-` panylng drawings.

Figure 1 is a front view and Fi 2 is a plan lllustrating the application o the inventlon to two seats, such as those used in clnema halls. Fig. 3 is a side view of said seats. Fig. 4 is a plan illustrating the preferred construction of the improved seat. Fig. 5 1s a part side elevation and part transverse section of the same construction of seat. Flg. 6is a plan of the relatively fixed plate of the seat.y Figs. 7 and 8 are ^v1ews, corresponding to Figs. 4 and 5, illustratlng a modified construction of the improved seat. Fig. 9 is a view of the relatlvely movable plate of the same construction of seat seen from below, and Fig.. 10 is a pllan of the relatively fixed plate of the sea In all of thefigures the same parts when of ldentical construction are indicated by the same reference numerals.

Referring first to the construction of seat shown in Figs. 1 to 6, 1 is a relatively fixed board or plate, hereinafter referred to as the fixed plate of the seat, which is either secured to the frames 2 of the seat, or, in the case of a tip-up seat, is pivotally supported by said frames. 3 is a relatively movable board or plate, hereinafter called the movable plate of the seat, and l is a slot formed in the plate 3. 5 is the seat proper secured to the plate 3. 6 is a sector-shaped plate, hereinafter referred to as the sector, which is secured to the fixed plate 1 and extends Ithe axis of Whichis coincident with the center from which is struck the sector 6, passes 'through a hole 11 in the fixed plate 1 and through the slot 4 formed in the movable plate 3 and is secured in positionby means of a nut 12 and washer 13. 14 is a coiled spring that is housed in the slot 4 and bears at its outer end against the front end of said bolt 10. 16 is a slot and t its fumer` end 'a aina block 15 l contacting with the stem o the bolt 10'. The

block 'is preferably made; of the shape shown, see particularly Fi 4, that is to'say is provided with a stem 15 that enters into the sprin 14, and with a head 15" the front face of w ich is curvedto correspond-to the face of the mova le'plate for the purpose of retaining the spring 14 in position in the slot 4.

fas

I plate3 backward. This y of the plate 3 may be effected either when The. mechanism described above acts as follows:

If the occupant of a seat has to move to allow a If he'swings his legsl towar his right side the length of wire ro e or the like 9 on the l left side of his-seat wi l wind itself on to the left hand half of the sector 6, while. the length of wire rope or the like 8 on the right side of his seat will become disengaged from the right handfhalf of' thesector 6. As a result of the movement given to his legs' by the occu ant of the seat the movable late 3, and t erefore the seat proper 5, Wilbe moved backward andalso to one side of its normal position. When said person has passed the occu ant of the seat the occupant swings his legs ack into their original position, and returns the'movable plate 3 to its original position, a movement which is assisted by the actionof the lspring 14. .If the occupant of thel seat swings his legs toward his left side similar actions will-take place, the length of wire rope or the like 8 on the right side of his seat winding itself on to the ri ht hand half of the sector 6 and the length og wire rope or the like 9 on the left side of his seat'becoming ldisengaged from the left hand half of the sector 6. The occupant of the seat instead of swingin his legs to either the right or the left ma?)1 orce the movable ackward movement the seat is in its normal position or when the seat has been partly rotated on the bolt 10.A The seat however is preferably merely swung to oneside, as this allows a passagewa o f greater width. u

lieferring nw to the modified construction of seat, illustrated by Figs. 7 ,to 10 of the accom anying drawings, it will be seen ymoved backward, or merel that the s ot 4 which allows a seat to be simultaneously swung on the bolt 1 0 and moved backward, is formed in the relatively fixed plate 1 of the seat, and the sector, 6, of the previously described construction of seat-is replaced by a disk 17, which is secured to the movable plate 3 .and is provided with a perigiheral groove 18, while the two lengths o wire rope or the like, 8 and 9, are re laced by a single length 19 of wire rope or t e like of loop shape, whichis anchored at its ends plate screwed to the upper person to pass in front of him he' swings his legstoward his ri ht or left side.

'to the fixed late 1 and is secured at its center to Vsaid isk. Otherwise the parts of the modified construction of theimroved seat arenthe saine as those shown in igs. 1 to 6 and are indicated @by the 'same reference numerals.'4

The partsof the modified seat coperate as follows:

If the occupant of a seat swin his legs to one or the other side the mova le plate 3 will simultaneously turn on the bolt 10 and move backward, the bolt 10 traveling in the slot 4 and compressin `the spring 14, while lthe half of the disk 1 on the opposite side,`

of the seat will become engaged to a greater extent with the half o fthewire rope or the ylike 19 4on the same side of the seat, and the otherhalf of said wire ro e or thelike, Abecomingslack, will be who ly or partl disenga d from the groove 18 formed in the peripI ery of thel disk 17. As in the case of the first described construction o-f seat, the

l(.:onstiuc'tion of I occupant of a seattted'withthe modified mechanism can move the seat backward either when the seat is in its normal position or when it has been partly vswung to one ioo mechanism interm'e iate between said relatively fixed and movable plates consistin of wire rope and of avperipherally-groove plate coperating with said wire rope and aving its axis coincident with the axis of saidl bolt, and al s ring for returning said movable plate to its normal position when dis laced` therefrom, substantially -as dej.
